SPRAYING PLANTS.

SPECIFICATION forming part of Letters latent No. 632,418, datedSeptember 5, 1899. Application filed December 14, 1898. Serial No.699,244. (No model.)

To all whont it may concern..-

Be it known that I, EZRA F. LANDIS, a citizen of the United States,residing at La Salle, in the county of Niagara and State of New York,have invented certain new and useful Improvements in Apparatus forSpraying Plants; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to apparatus for spraying plants; and it consistsin the novel construction and combination of the parts hereinafter fullydescribed and claimed.

In the drawings, Figure 1 is a side View of the complete apparatusworked by a man. Fig. 2 is a longitudinal section through the air-pump,drawn to a larger scale.

In applying poison to plants to kill insect life it is desirable toapply the poison in liquid form under pressure and in the form of a finespray instead of merely pouring it on the plants, and it is alsodesirable for the operator to have both his hands free to work thespraying apparatus.

A is a man.

B is a reservoir for the liquid poison, and G is a reservoir forcompressed air.

D is a spraying device of any approved construction connected with thereservoirs B and C by flexible tubes b and 0, provided with suitableregulating-valves. The reservoirs B and O are portable and are attachedto the body of the man in any approved manner. The spraying device islight and portable, so that it may be carried by one hand and turnedabout in any direction.

E is an air-pump for supplying the reservoir O with compressed air. Thisair-pump is secured to the man and is operated by his movements in theact of walking. The cylinder E of the air-pump is provided with a plateor bracket 6 on one side, which projects under the mans foot, and c is astrap or other fastening device for rigidly securing the cylinder to themans leg. F is a piston slidable in the said cylinder and provided withadownwardly-projecting rod f for operating it in one direction. F is aspring or springs which operate the piston in the other direction andcause the said rod to project from the lower end of the cylinder. Theair-pump is provided with an inlet-valve g and an outletvalve 9. I

G is a flexible pipe which connects the outlet-Valve with theair-reservoir.

Every time the man takes a step forward the rod is forced upward bycontact with the ground and a charge of air is forced up the pipe G intothe reservoir.

If desired, two similar air-pumps can be used and can be secured one toeach leg of the man.

The apparatus may be variously modified in carrying out this inventionand the airpump may be secured to the man in any approved manner, so asto utilize the natural movements of his body in moving from place toplace.

When the apparatus is used for spraying trees, the motion of a horse inWalking may be utilized for working the air-pump and the spraying devicemay be manipulated by the rider. The foot-plate on the air-pump canproject under the shoe of the horse in a similar manner to thathereinbefore described, or the air-pump can be attached in any otherapproved manner.

I do not confine myself to the use of the airpump for the purpose ofdestroying insect life on plants, as the air-pump when thus operated bythe natural movements of an animal, whether man or horse, may be usedfor a variety of purposes.

WVhat I claim is 1. The combination, With portable reservoirs for liquidand for compressed air, and means for attaching said reservoirs to anoperator; of an air-compressing device, means for connecting the saiddevice to one of the limbs of the operator, whereby the air-reservoir isreplenished with air by the motion of the operator while walking, aspraying device, and connecting-pipes, substantially as set forth.

2. The combination, with portable reservoirs for liquid and forcompressed air, and means for attaching the said reservoirs to anoperator; of an air-compressing device,means for securing the saiddevice to the foot of the operator so that a charge of air is forcedinto the air-reservoir at each step, a spraying device, andconnecting-pipes, substantially as set forth.

3. The combination, with portable reser- Voirs for liquid and forcompressed air, a spraying device, and pipes connecting the said parts;of a portable air-pump cylinder connected with the said air-reservoirand provided with a laterally-projecting foot plate or bracket and meansfor securing it to'the limb of an animal, and a spring-operated pistonprovided with a rod which projects from the lower end of the cylinderand forces the piston upward by contact with the ground at each step,substantially as set forth.
